SEVE-CLEANER BRUSH.

Application lerl January 20, 1908.

To all whom it may concern:

Be it known that l, ADOLPH EWIENS, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of FViscensin, have invented certain new and useful Improvements in Sieve- CleanerBrushes; and l do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to brushes of the class set forth in my Patent No. 711,141, granted October 14, 1902, as designed for employment in shaking sieves of peculiar construction to automatically clean the screen cloth of same; the object of the present invention being to provide simple, economical, light, durable, rapidly moving and elastic sieve-cleaner brushes that are highly ellicient in their operation and not liable te damage sieve-frames or the linings of same.

Hence said invention consists in certain peculiarities of construction and combination of parts hereinafter specified with reference to the accompanying drawings and pointed out in the claims.

Figures l and 2 of the drawings represent sectional viens of a sieve-cleaner brush in accordance with my invention, these viens being respectively indicated by lines 1-1 and 2 2 in Fig. 3. Fig. 3, a plan vienv of the brush; Fig. 4, a similar viev.' of a fragment of said brush illustrating a continuous tutt-holder, and Fig. 5, a sectional vier.v indicated by line 5-5 in Fig. 4.

Referring by letters to the drawings, A indicates a conical helix of spring-wire, the ends of Which are preferably bent inward and at such angles as not to come into contact With the Wire bottoms or cloth tops of shakingsieves, said helix being the preferred form of an elastic buffer-frame in my improved sievecleaner brush. Soldered, seanied or otherwise fastened to the upper Wind of the helix is one or more strips B of sheet-metal, each constituting a holder for bristles or other suitable brush-material C folded therewith, as shown in Figs. 1 and 5, the free portion of said brush-material being upwardly extended to attach the cloth of the sieve in which the brush is employed.

The lower nind of the helix: is suitably bent to form rockers l) that contact with the bottom of the sieve, and owing to the pecul- Specication of Letters Patent.

Patented March 9, 1909.

Serial No. 411,589.

iar forni of the brush frame it presents the least possible surface to the frame or frame lining of said sieve.

The brush-material C is shown in the form of tufts distributed at intervals of the upper wind of the helical elastic buffer frame of the brush, there being a plurality of tuft holders shown in Figs. 1 and 3, but a plurality of tufts may be employed in connection with a single holder designed to extend approximatel t the Whole length of the un Jer Wind of the brush-frame, and this single continuous holder may be filled throughout with bristles or analogous brush-material if desired. rl"he single holder for the brush-material C is preferably seemed on the brush-frame, this being an expeditious and economical way of mal:- ing the connection, slipping of holder being impossible.

lllhile a conical helix has been shown as the preferred form of elastic buffer-frame of the brush, said frame may be a spirally ascending coil of any arbitrarily selected form without departure from an essential generic feature of my invention.

l claim:

1. A sieve-cleaner brush comprising an elastic buffer-frame in the form of a conical helix, and brush-material secured in connection with the '-.ipper Wind of the frame to extend upward therefrom.

2. A sieve-cleaner brush comprising an elastic buffer-frame in the form of a conical helix, a holder in connection with the upper Wind of the frame, and lnush-material secured in the holder to extend upward therefrom.

3. A sieve-cleaner brush comprising an elastic buffer-frame in the forni of a conical helix, a sheet-metal strip seained on the upper Wind of the frame, and upwardly extend.- ing brush-material held in folds of the strip.

4. A sieve cleaner brush comprising an elastic buffer-frame in the form of a conical helix having rockers depending from its lower Wind, and brush-material secured in connection with the upper wind of the frame to extend upward tl'lerefrom.

5. A sieve-cleaner brush comprising an elastic butler-frame of spring-wire Wound in the form of a conical helix and the lower Wind thereof bent to form depending rockers, and brush-material secured 1n connection with the upper Wind of the frame to eX- tend upward therefrom.

6. A sieve-cleaner brush comprising an elastic buffer-frame in the form of a conical 5 helix, and a plurality of tufts of brush-material connected at intervals to the upper Wind of the frame to project upward therefrom.

7. A sieve-cleaner brush comprising an elastic buffer -frame of spirally ascending 10 coiled material and upwardly extendingV brush-material secured in connection with the frame.

In testimony that I claim the foregoing l have hereunto set my hand at Milwaukee in the county of Milwaukee and State of Wisl5 consin in the presence of two witnesses.
